Design of Thyristor Valve assembly in On-load Automatic Capacity Regulating Distribution Transformer

摘要

The working principle of on-load automatic capacity regulating distribution transformer is elaborated in this study, a layout scheme with anti-parallel thyristor valve assembly as capacity regulating switch is designed. The thyristor valve assembly is selected. The respective character in the system of electromagnetism trigger and online monitoring as well as photoelectricity trigger and online monitoring is described. With the comparison, it takes the system of electromagnetism trigger and online monitoring at last.
